循环跳跃:从大容量紧化论软项

Jumping Through Loops: On Soft Terms from Large Volume Compactifications

Marcus Berg, Michael Haack, Enrico Pajer

摘要:

我们在弦论中对现象学上成功的hep-th/0502058大体积方案进行了第一次一致性检验。特别地,我们考虑弦有效作用量的展开是否在D-膜和O-平面的存在下是一致的。由于树级的无尺度结构,该方案是令人惊讶的强大。我们计算了软超对称破缺项的修正,只找到了次引导修正。我们还评论说,对于大体积的限制,环形orientifolds和纤维卡-丘流形的校正可能是更重要的,我们讨论了进一步的检查,需要进行。

英文摘要:

We subject the phenomenologically successful large volume scenario of hep-th/0502058 to a first consistency check in string theory. In particular, we consider whether the expansion of the string effective action is consistent in the presence of D-branes and O-planes. Due to the no-scale structure at tree-level, the scenario is surprisingly robust. We compute the modification of soft supersymmetry breaking terms, and find only subleading corrections. We also comment that for large-volume limits of toroidal orientifolds and fibered Calabi-Yau manifolds the corrections can be more important, and we discuss further checks that need to be performed.
